Help

My magneto isnt working properly.

not really sure how it works, but it doesnt always make the snapping noise and thusly no spark when it happens.

is there a place i can get a mechanical breakdown pictures and specs so maybe i can fix this thing??

or maybe i need to get a rebuilt magneto or at least one that works.

mine is an FMJ magneto on a 1946 allis B tractor.

any help will surely be appreciated.

Thanks

Tom
